RU2296589C2 - Device for inhaling hypercapnic mixture - Google Patents

Abstract

FIELD: medical engineering.

SUBSTANCE: device has rigid mask of 0.8 l by volume. Nose, mouth and chin are introduced into the mask. The mask has articulated support member attached to it for having rest on the nose. Rubber member movable in fastening mask holes is available for fixing the mask on head. Space between the mask and face and pressure against the face are controlled with the movable member.

EFFECT: facilitated breathing mixture selection.

Description

The invention relates to medical equipment and can be used for the treatment and prevention of respiratory, circulatory, digestive. A device is known according to copyright certificate CCCP No. 1607817 A1, in which the respiratory mixture is formed due to its own exhaled air and inhaled atmospheric, mixed in a mixing chamber consisting of a large number of parts (more than 8 pieces), having large dimensions, a scale indicating carbon dioxide concentration gas in the inhaled mixture, equipped with an adjustment valve. It is known that the concentration of carbon dioxide in all devices of this type depends on the capacity of the mixing chamber, the inspiratory and expiratory volumes of the patient, and the metabolism in the cells of the body. All these components of the respiratory process, including blood circulation, are constantly changing. In order to maintain the carbon dioxide concentration value set on the scale in the mixing chamber, the valve must be constantly moved, and the calibration scale does not affect metabolism, respiration and blood circulation, therefore, these details are unnecessary.

The technical task of the invention is the development and creation of a device that allows the patient, without harmful drugs, to restore the normal concentration of carbon dioxide in the alveolar breathing mixture and blood by mixing their own expired air with atmospheric. The device should be simple, lightweight, suitable for use during asthma attacks, angina pectoris, blood pressure, for the prevention of diseases, at rest, movement, as a lung muscle trainer.

This problem is solved by the invention of a device for breathing a hypercapnic respiratory mixture, containing a mask, characterized in that the mask is rigid, is a mixing chamber and has a capacity of up to 0.8 l for immersing the nose, mouth and chin, while the mask is equipped pivotally mounted on it with a support for support on the nose and an elastic band for fixing on the head, which can move in the mounting hole of the mask, adjust the gap between the mask and the face and hold the mask to the face, characterized in that It provides the ability to control the concentration of carbon dioxide in the breathing mix to 3 vol.%.

The drawing shows a device for breathing a hypertonic breathing mixture containing a mask 1, characterized in that the mask 1 is rigid, is a mixing chamber and has a capacity of up to 0.8 l for immersing the nose, mouth and chin, while the mask is pivotally mounted it with a support 2 for resting on the nose and an elastic band 3 for fixing on the head, which can be moved in the mounting hole of the mask, adjust the gap between the mask and the face and press the mask to the face, which allows you to change the depth of immersion of some and into the mask, thereby changing the net capacity of the mask, and consequently, the concentration of carbon dioxide in the respiratory mixture of the device, patient’s lungs, and arterial blood.

Device operation

The patient immerses 1 nose, mouth, chin in the mask, with an elastic band 3 fastens it on the head, begins to breathe. He feels that he adjusts the gaps between the face and the mask with gum 3, which changes the net volume of the mask, the inhalation-expiration resistance and the concentration of carbon dioxide in the respiratory mixture of the mask to 3 vol.% Depending on the volume of respiration and metabolism, which helps to increase the content carbon dioxide in the blood from session to session, and over time to adapt the respiratory center to normal breathing, restore normal levels of carbon dioxide in the blood (6.5% vol.), cure diseases without the use of harmful medications.

To relieve asthma attacks, angina pectoris, blood pressure, patients breathe in a mask for 30-40 minutes. To prevent disease, you need to breathe in the mask at least three times a day for 1 hour: in the morning, at lunch and in the evening. You can breathe in motion, at rest, during sleep. The total duration of therapeutic respiration is until complete recovery of health and depends on the severity of the disease and the patient's will.

Control of recovery - holding the breath in a calm state after exhalation for at least 60 seconds or by determining the minute volume of breathing in a calm state using a sealed bag of known capacity, put on hermetically by mouth and filled with exhaled air for a certain time when inhaling with the nose, and exhaling into the bag through the mouth. According to the textbooks of human physiology, the minute volume of breathing in a calm state, equal to 5 l / min, is considered normal, which corresponds to the normal content of carbon dioxide in arterial blood, if more - disease.

The present invention can be used as a simulator - a sports simulator by adjusting the cross-section of the gaps with an elastic 3, increasing the resistance to inhalation-exhalation increases the load on the muscles of the lungs similarly to the results from physical education.

The advantages of the proposed breathing device hypercapnic mixture - simplicity (only three parts), lightness, versatility, can be used at rest, movement, to relieve seizures, for the prevention of diseases, training of lung muscles.
